Reduced MTUS1 expression is also associated with poor prognosis in lung adenocarcinoma [11], gallbladder adenocarcinoma [12], renal cell carcinoma [13], bladder carcinoma [14,15], adenoid cystic carcinoma of the salivary gland [16], and squamous cell carcinoma of the tongue [17]. Here, MTUS1 is linked to salivary gland adenoid cystic carcinoma.
